Numerous allegations of bribery and corruption have been levelled since FIFA announced in December 2010 the Middle Eastern country would host football's biggest spectacle.

But Lee, who also worked on the London 2012 Olympics bid, insists it was no different to any other he had worked on.

"There have never been any accusations that have produced evidence about bribes being paid," he said.

"I think the most recent coverage with France Football told us that there was government to government conversations going on, but in modern bidding that is normal.

"London 2012 won partly because of Tony Blair, Sochi 2014 won partly because of Vladimir Putin, Rio 2016 won partly because of President Lula.

"I certainly think there was evidence that governments were talking to governments but I don't see how that's different from most of the winning bids in recent times."

The London Games were hailed a success last year after many doubted the city's ability to host an Olympics.

The success of the Games proved doubters wrong, with fans and athletes equally impressed at Britain's hospitality.

Attention has turned to the legacy the Games will have on London's future, but Lee said it was too soon to tell.

"In some ways you can't judge the legacy of an Olympic games until 10 or 15 years after it has happened," he said.

"It would be wrong to rush into judgements.

"I think they are things that have clearly been delivered in terms of the venues, regeneration of the east end of London and certainly in terms of elite sport we have had more success as a result of London 2012."
